  • The diagnosis of pattern identification in Korean Medicine depend on Korean Medicine doctor's experience and information. So, Pattern identification in Korean Medicine raise a question of objectification. This study is to standard stroke pattern identification in Korean Medicine. Weight of symptoms was given important(1points), very important(2points) by stroke specialist. So weight of symptoms is used two method. One is total sum and the other is total man. One had been compared Pattern identification between diagnosed patients by medical specialists and by applicated weight in case report form. The other had been compared Pattern identification between intersubjectivity by medical specialists and by applicated weight in case report form. It is 38%(total sum) or 40%(total man) concordance rate between diagnosed patients by medical specialists and by applicated weight in case report form. It is 82.4% concordance rate between intersubjectivity by medical specialists and by applicated weight in case report form. To acquire more concrete data on this theme, we need further and large scale of prospective researches.

  • In this study, we analyzed the erosion variation of beach area at Haeundae Beach after coastal improvement project using video monitoring system operated by the Coastal Erosion Monitoring (Ministry of Oceans and Fisheries). Haeundae Beach was well maintained and stabilized following large scale nourishment through coastal improvement project despite of seasonal fluctuations. However, multiple typhoons over the last two years caused beach stabilization patterns and seasonal fluctuations to lost equilibrium, resulting in rapid erosion. In particular, the sandy beach was eroded by typhoon Solic and Kongray in 2018 and failed to recover beach area in winter by seasonal fluctuations. And due to multiple typhoons in 2019, the beach area was reduced 9.5 % (12,607 ㎡) year-on-year. According to analyze the observed wave and beach area data in Haeundae, the tendency of erosion and sedimentation was influenced by seasonal incident wave direction for each section(west, center and east part). Therefore, to identify the causes of decreasing seasonal fluctuation characteristics and continuous erosion, hereafter, more precise monitoring of different factors are needed, such as the crest heights of submerged breakwater and its loss of function, and sand leakage to the outside around submerged breakwater.

  • To guarantee the long-term access to digital material, digital preservation needs to be systemized, and detailed investigation on cost elements of digital preservation should be done for the continued support of budget. To meet the needs in this area, this paper categorized the digital preservation cost into direct and indirect cost through deriving common elements used in prior research on this issue. For case analysis, two institutions, representing domestic University Library and National Library of Korea under large-scale digitization currently, are selected to analyze the current status of digital preservation and estimate the preservation cost. The case analysis shows the systematic preservation function should be performed to guarantee the long-term access digital material, even though a basic digital preservation is currently conducted. It was projected that the digital preservation cost for the two libraries, accounting for $11.8\%$ and $8.6\%$ of digitization cost, respectively, should be injected every year. However, the estimated figures are very conservative, because the cost for estimating the preservation function, such as installing digital repository and producing meta data, was excluded in the estimation. This proves that digital preservation is a synthetic activity linked directly and indirectly to various activities from production to access of digital object and an essential costs that should be considered from the beginning stage of digitization project.

  • The purpose of this study was to help improve the quality of education to keep up with fast-changing environments in educating sector. Relevant literature and data were reviewed, and the subjects in this study were dental hygiene juniors at seven two-year colleges in the Seoul metropolitan area and other regions, on whom a survey was conducted for about three months from August through October, 2004, to assess their satisfaction level with their major and educational environments. And it's concluded that in order to attract more new students and foster qualified students, dental hygiene practice labs should be improved on a large scale, and that there should be a great deal of investment in teaching facilities. The major findings of the study were as follows: 1. As for satisfaction with major choice, 57.5% of the students investigated, the largest percentage, expressed satisfaction with their major. 27.8%, the second largest group, found their choice not to be bad. 2. Regarding satisfaction with the state of practice labs, 41.9% were pleased with practice labs. This rate was quite lower than that of nursing students, as 64.2% of nursing students were pleased with their practice labs.7) 3. As to satisfaction with individual practice labs, oral prophylaxis labs were considered most satisfactory, as 53.9% were satisfied with them. Digital radiation labs appeared to be satisfactory the least, which made 77.0% dissatisfied. 4. Whether there were any connections between their working experience as a clinical worker and satisfaction level was investigated. In terms of their satisfaction with major choice and the state of practice labs, the students who had ever worked as a clinical worker were relatively pleased with the state of practice labs. As for satisfaction with each practice lab, those who had ever served as a clinical worker before being admitted into college expressed more satisfaction with radiation practice labs(p<0.05) and digital radiation labs(p<.05) than the others who hadn't. The gap between the two was statistically significant. 5. In regard to the causes of dissatisfaction with practice labs, 93.7 and 80.0% were respectively dissatisfied with digital radiation labs and basic dental hygiene labs because their colleges were devoid of those labs. 51.6%, the largest group, found oral prophylaxis labs unsatisfactory because of their frequent breakdown. In the event of most of the other practice labs, the greatest percentage were discontented due to a shortage of equipment.

  • In order to understand the population dynamics of red tide dinoflagellate Noctiluca scintillans, we examined its hydrographical and bio-ecological characteristics at 19 to 20 stations of Gwangyang Bay during all four seasons from 2010 to 2012. During the 3-year period, N. scintillans was seasonally abundant during summer with water temperatures ranging from $15^{\circ}C$ to $22^{\circ}C$ and salinity ranging from 25 psu to 30 psu. On the other hand, N. scintillans population density significantly decreased in spring, fall and winter, although they were present even in lower temperatures (< $4^{\circ}C$). However, high water temperature (> $27^{\circ}C$) and low salinity (< 12 psu) led to the disappearance of N. scintillans population. Chl-a concentration in winter, spring and fall was positively correlated with N. scintillans population density, whereas the N. scintillans population was negatively correlated with Chl-a concentration in summer. This implies that densities of prey population such as diatoms are one of important contributing factor for maintaining abundance of N. scintillans in winter, spring and fall and for increasing abundance of N. scintillans in summer. During summer season, bio-accumulation of N. scintillans population by the wind from southwest is also considered to be a key factor in triggering the formation of large-scale blooms in Gwangyang Bay.

  • This study examined the relationships among levels of knowledge, attitude and preventive behavior regarding tuberculosis in service workers. The survey period was 1 - 7 October, 2015 with service workers who work in large scale stores in Jeonnam. The collected data were analyzed using an independent t-test, ANOVA, and Pearson's correlation coefficients using the SPSS WIN 12.0 program. The mean score for knowledge about tuberculosis was $14.05{\pm}6.39$, the mean score of attitude toward tuberculosis was $29.87{\pm}4.89$ and the mean score of preventive behavior for tuberculosis was $31.44{\pm}4.86$. Preventive behavior was found to have significant relationships with gender, marital status, smoking, job satisfaction, and subjective health status. A slightly positive correlation was observed between the knowledge of tuberculosis and the attitudes toward tuberculosis. A positive correlation was noted between the attitude toward tuberculosis and preventive behavior for tuberculosis, while there was a negative correlation between the preventive behavior and age. Therefore, is necessary to consider the related factors for the development and implementation of systematic education programs that can encourage and promote preventive behavior for tuberculosis among service workers.

  • In what way is the urban landscape of North Korea used today, and what features do people prefer in the North Korean landscape? This study analyzed the characteristics of Pyongyang landscapes and their effects, based on an analysis of Western tourists motivation for tourism in North Korea and preferred enjoyment-seeking experiences. Using data from the tourist agency specializing in Western tourism in North Korea and a location based photo-sharing service, the study interprets the visual distinctiveness of Pyongyang landscape. The study concluded that widely known risk to travelers in North Korea is in fact an attraction, making people want to visit directly. However, this risk was mitigated in practical experience by the overall intermediation of the tourism agency and locals' conscious behavior to keep their distance from foreigners. Next, the scope of National ritual attributes was expanded to the locals' daily life as well as large-scale events such as mass games and military parades only if for national holidays. Also, the most preferred factors contributing to North Korean tourism were based on departure from routine through mobilization of the residents. This indicates the extension that the nature of North Korea as a theater state. The Pyongyang landscape represents a world politically isolated, people's congregated motion to display to the world, and people's lives hidden beneath a veil. These visualities fulfill the fantasy of Westerners regarding North Korea. Furthermore, these are superficial images that help create a basis to maintain the North Korea regime.

  • The production of larger of ships is a survival strategy for global shipping companies to pursue the economics of scale. According to this strategy, to respond to this situation, many containers are loading/unloading simultaneously in the hub port. Additionally, the container terminals are promoting the introduction of automation to expand the terminal facilities and increase efficiency/productivity of the container yards. European ports have introduced automation to address rising labor costs and shortages of labor. Recently, the construction of fully automated container terminals is increasing in the United States and China to resolve problems such as the slow growth of the global economy, the emergence of large ships, air pollution, and safety accidents. Domestic ports are at an early stage compared to the world's advanced container terminals, and countermeasures are being prepared to respond to the changing ports. However, research on the recognition difference analysis that examines the opinions of stakeholders is insufficient. As a result of analyzing the recognition among the groups, it was found that container terminal operators reduced labor costs, improved shipping services for shipping companies, prevented safety accidents for port union labor, and increased service for port authority and government agencies. Thus, to closely examine the perception among the groups, one-way ANOVA was performed, and then the implications were deduced as the basic data for the smooth introduction of automation.

  • Disasters that occur most frequently in rural areas are drought, flood, damages from wind and cold weather. Among these, damages from storm and flood and drought are the main disasters and recently, these are occurring on a large scale due to unusual weather conditions. Under such circumstances, projects and researches on disasters in rural areas are under way but they are mostly targeting one area or making approaches focusing on repair facilities, maintenance project of facilities in small streams, and disaster management, so there have not been enough studies on the current status of overall damaged facilities in the rural areas. Against this backdrop, through the analysis of the current status of damaged facilities due to storm and flood in rural areas, this study aims to provide base data for policies needed for disaster recovery planning and maintenance work of rural areas. For the analysis of damaged facilities due to storm and flood in rural areas, using the annual report on disasters issued by Ministry of Public Safety and Security and based on the occurrence rate of estimated damage in each city and district for the past 10 years(2004~2013), 8 areas with the highest number of occurrence and cost of damage were found from each province and target areas were selected. Then, regarding the selected target areas, the General Plan for Reducing Damages from Storm and Flood, which is the report on top-level plan for preventing disasters, was secured and the current status of damaged facilities were analyzed. After organizing the analysis of current status, the tendency of damaged facilities due to storm and flood in rural areas, the items of damaged facilities depending on the types of storm and flood damages, and risk factors were suggested. Based on this result, in order to generalize the results of follow-up researches, it is thought that disaster recovery planning and establishing the system of remodeling items necessary for maintenance work would be possible by analyzing damage investigation items recorded in additional researches on rural areas, researches on natural disasters, and recovery plan instructions and by conducting on-site investigation on the damaged villages from storm and flood in rural areas.
